Yes, I have problems with fresh fruits and veggies, too. They make the roof of my mouth swell and itch, as well as the back of my throat, sometimes. I can get some intestinal issues, as well. Best not to go into that. Suffice to say it is bad enough to make me not eat things I love.
I can eat a little bit of...
Lemos/likes - never tried to eat one, but do fine with them in water.
...but that's it. Sometimes I think smelling melons will make me sick.
And I can't eat a ton of them in one shot. But if you stick them into sugary syrup, like peaches in a can, I could eat as many as I wanted.
Veggies...I just don't eat any fresh. They have to be cooked in some way.
I don't understand it all. I just know what I can and can't eat.
Some people don't believe it. They think I'm lying, creating an excuse not to eat things I don't like. As if I stopped eating bananas because I suddenly started not liking them, lol. Another example of people being dumb. It happens.
